Solar cells: Losses made visible on the nanoscale

Solar cells made of crystalline silicon achieve peak efficiencies, especially in combination with selective contacts made of amorphous silicon (a-Si:H). However, their efficiency is limited by losses in these contact layers. ...

Light-emitting silicon for photonic computing

If computers transmitted data using photons instead of electrons, they would perform better and use less power. European researchers are now studying a new light-emitting alloy of silicon and germanium to obtain photonic ...
